    Hi All,

    Can someone interpret these router statistics? What unit of measurement is MiB?


    LAN : 1.76 RX / 7.91 TX (MiB)
    WLAN : 23.73 RX / 275.51 TX (MiB)
    WAN : 12.32 RX / 1.88 TX (MiB)

    IEC International Standard names and symbols for prefixes for binary multiples for use in the fields of data processing and data transmission:

    one mebibyte 1 MiB = 1 048 576 B

    one megabyte 1 MB = 1 000 000 B

    Quote from link:

    "Historical context*
    Once upon a time, computer professionals noticed that 210 was very nearly equal to 1000 and started using the SI prefix "kilo" to mean 1024. That worked well enough for a decade or two because everybody who talked kilobytes knew that the term implied 1024 bytes. But, almost overnight a much more numerous "everybody" bought computers, and the trade computer professionals needed to talk to physicists and engineers and even to ordinary people, most of whom know that a kilometer is 1000 meters and a kilogram is 1000 grams.

    Then data storage for gigabytes, and even terabytes, became practical, and the storage devices were not constructed on binary trees, which meant that, for many practical purposes, binary arithmetic was less convenient than decimal arithmetic. The result is that today "everybody" does not "know" what a megabyte is. When discussing computer memory, most manufacturers use megabyte to mean 220 = 1 048 576 bytes, but the manufacturers of computer storage devices usually use the term to mean 1 000 000 bytes. Some designers of local area networks have used megabit per second to mean 1 048 576 bit/s, but all telecommunications engineers use it to mean 106 bit/s. And if two definitions of the megabyte are not enough, a third megabyte of 1 024 000 bytes is the megabyte used to format the familiar 90 mm (3 1/2 inch), "1.44 MB" diskette. The confusion is real, as is the potential for incompatibility in standards and in implemented systems.
    Faced with this reality, the IEEE Standards Board decided that IEEE standards will use the conventional, internationally adopted, definitions of the SI prefixes. Mega will mean 1 000 000, except that the base-two definition may be used (if such usage is explicitly pointed out on a case-by-case basis) until such time that prefixes for binary multiples are adopted by an appropriate standards body.

    Thank you yes I am familar with the origin of Mb and MB. What is a mebibyte? And back to the original question what is MiB?

    Isn't MiB involved with SNMP traps?

    Did you bother reading his answer to you, before asking exactly the same thing again? Go back and read the beginning of his reply - he gives you the answer and even provides you a link with more information in it.
